BM-800 Mic support group opened.
May 31st, 2016 | 
Author: Due to the intense traffic and interest in the BM-800 Microphone modification, and the amount I have noted sold since the last Blog. I have opened a support group on Facebook for anyone interested using them for Amateur radio purposes..
https://www.facebook.com/groups/116507002103281/
Please note this is a Closed group. Anyone can find the group and see who's in it. Only members can see posts.
As well as the the G4IZH modification, it will be interesting hearing your own thoughts and modifications plus any further ideas. Even if you just run a BM-800 into a simple audiomixer please join the group to help others.

Really cheap cheap BM-800’s!
For those of you who read my BM-800 microphone, G4IZH modification Blog I wrote early April. A UK ebay seller is currently selling the BM800 at a silly price of £6.99 ($10) including UK delivery! These are branded Floureon BM-800 and are the same specification as the 48V ones I have already mentioned, making them ideal for conversion as the details on the link above or using straight into an audiomixer.
The price proved so irresistable, I decided to purchase another pair and they arrived boxed with all the accessories within a couple of days of clicking the mouse:
Really the price is so stupid, you could fill the cupboard with a load. If you make a mistake with the mods or a slip with the soldering iron you are not going to end up red faced or feel it on your pocket. The G4IZH project is now really viable for a club, to get your heads together, purchase a load and have a modification night.
Link to seller here.
* Please note this is a UK seller and I don't know if they ship internationally? I have no connection with this company only to spread you Amateurs with the news.

(3/7/16) The offer has now ended, so I have removed the sellers link. Hope you got yours?

Windows 7 says it’s last goodbye!
Last night I switched on the PC it booted into Windows 7 as normal, after a quick look around at a few Ham sites I was called for my tea. After returning to my desk after eating my roast beef and Yorkshire puds I returned to something new!
Unknowing to me Windows 10 had downloaded in the background and installed itself on my PC without even informing me. Yes, Microsoft can take over your machine without you even knowing! It appears if you have got your settings set for auto updates it will do this. Beware! Big brother is really alive! Would Microsoft like it if I came in through the back door and took over their servers and PCs, I think not!
I must admit though, there were only a couple of little hiccups which I sorted in an hour or so, everything seems to have gone over clean. It appears you can revert back to your previous operating system but only within 30 days of the install.

BM-800 Mic something to talk about.
The BM-800 microphone has been around for a few years, search ebay and an abundance of them will flood your screen. The BM-800 and 700 versions are produced in China, the BM-700 version only has slight cosmetic differences but is basically the same. The BM-800 is well constructed for a price of around £10 "including delivery" putting most expensive commercial microphones to shame for price! Infact you could buy a score of BM-800's to one well known branded studio microphone.
Until recently there were two types of the BM-800 available, one version was badged Shengyue BM-800, this had the advantage of an onboard 1.5V battery to feed the condensor insert. Thus the great advantage of this no external supply was required. This model has now become as rare as hens teeth and we are left with the 48V version. This type however requires an external 48V voltage fed up the cable to charge the insert. Some have overcome this problem using the microphone with an external audio mixer and feeding it using the 48V phantom power supply from the mixer. There is also another problem, the audio output is balanced, and again if not using a mixer you have got to find a method of changing it's output to unbalanced to feed your rig.
I have a couple of these microphones still wrapped up in their boxes and have been thinking for sometime how I could match them straight into my radio's without using a mixer etc.
Until recently there had been very few modification ideas around for this model, but a few nights ago I stumbled across a website from Pete G4IZH who has not only done all that is required to convert the mic from 48V to around 9V that can be taken from your radio's external mic socket supply, or even using a 9V battery, which could be made to fit inside the BM-800 case. The board has then been hacked, to get rid of the balanced output and then fed directly into a filter to tame the HF and LF response ranges, making it more ideal for Amateur requirements. Of course you don't have to do it quite the same, especially if you want to fit a PP3 battery inside the case a bit more room will be required, but all the information is now there to customize the idea to your own requirements.
